tious and possesses many of the desirableproperties of this fruit.

Dried plums, and particularly dried prunes which are a variety of plums, have long been valued for their dietary propertiesas well as for their demulcentand laxative properties both in raw condition and when stewed. v

As the resultof extended experiments, I

have discovered that plums containing considerable fruit sugar and particularly prunes which are known to be rich in sugar may be madeto yield a soluble solid extract from which a palatable beverage may quickly be are ared iossessin in a marked de ree, '57 h the valuable dietary and other well known properties ofthis fruit.

While the various forms of edible plums may be used for the preparation of the extract, I prefer to use prunes because of their large content in sugar which lends itsclfto caramelization and because of the wide recognition of the valuable properties of this fruit.

' Specification of Letters Patent.

By way of illustrating one ay in which 5 the benefits ofmy invention may be secured, dried prunes as they are found on the market are dried at temperatures suiiicientto render them friable and are then roasted, the temperature being sufficient to caramelize the sugar contents and preferably sutlil Patented uly 22, 13.93135.

60 (1, thereby usually obtaining a clear solution. Should the solution not be clear, filtration is resorted to for this purpose. The: clear aqueous solution-is next concentrated by evaporation to a solid. This operation is preferably conducted in a vacuum pan or on a rotary drum in. cacao, the usual precaution well-known to those skilled in this art being taken to prevent injurious heating of the product. The dried extract is then conuninuted or reduced to grains, powder, flakes or other subdivided form and is dy for packing. Instead of subjecting the prunes as a whole to the roasting operation, the pulp may be roasted alone, in which case the pulp and stones may be separated for example by stewing and straining or in any other manner. I prefer, however, to practice the process as above described. since the flavor of the solid extract is improved by the presence of the kernels and pericarp with the pulp in the roasting step; and also because the water extraction is facilitated by the presence of this more or less cellular material. The resulting product is a beverage extract of extreme solubility in water, either hot or cold. is palatable and possesses the nutritious and, to a certain extent. the laxative qualities of the prunes from which it is made.
